Shopify AMP pages are causing duplicate content in Google

AMP apps (FireAMP, RocketAmp, Ampify Me and similar) generate a parallel /amp version of your product, collection and blog pages. Each AMP page must carry a rel=canonical back to the standard URL and the standard page should reference it with rel="amphtml"; if those tags are missing or wrong, Google can index both versions and treat them as duplicate content. After you uninstall the AMP app the /amp URLs often stay indexed and then 404. Shopify has no native AMP support and keeps no record of the injected tags, so removing the app does not clean up what Google already indexed.

If you didn't already have a backup, those old values are gone — Shopify keeps no history.

The steps below recover what you can. To make the next time a 1-click undo instead of hours of CSV work: a daily snapshot of every SEO field. Free to monitor, no card — and SEO Vault only reads your store unless you click restore.

Step by step

  1. Stop the source: decide to keep AMP or drop it. If dropping it, uninstall the AMP app and confirm the /amp routes no longer resolve; if keeping it, verify every /amp page has a correct rel=canonical pointing to its non-AMP URL.
  2. Clean up the index: in Google Search Console use the Pages/Indexing report to list the indexed /amp URLs, fix or add canonicals so Google consolidates them to the main page, and use the Removals tool only for urgent duplicates.
  3. Redirect the dead AMP URLs: because /amp paths live on your own store domain (unlike CDN image URLs), create Shopify URL redirects (Online Store > Navigation > URL Redirects) from each /amp path to its canonical page; use the Wayback Machine or Search Console to enumerate which AMP URLs were indexed.
  4. Prevent silent regressions: SEO Vault keeps a daily snapshot of your canonical tags, handles and meta fields and alerts you when an app injects or changes them — so duplicate-content tags are caught the day they appear and your correct SEO fields stay a 1-click restore.
